Motor protection breaker, 0.25 A, CLASS 10, spring terminals
Its thermal overload release is adjustable from 0.18 to 0.25 A, and the magnetic short-circuit release trips instantaneously at 3.3 A. Breaking capacity is a flat 100 kA across the full voltage range: 240 V, 400 V, 500 V, and 690 V AC. The unit includes factory-fitted transverse auxiliary contacts: 1 NO + 1 NC, rated for 100,000 mechanical/electrical operations.
RoHS compliance date is noted as 10/01/2009, meaning the design meets EU Directive 2002/95/EC. No separate UL or CSA listing appears in the spec record, but the SIRIUS range typically carries IEC/EN 60947-2 and 60947-4-1 approvals; verify the specific certification mark on the unit if your panel requires UL 508 listing.
Panel integration and fit
Snap-on DIN rail mounting, no tools needed. Side-by-side mounting requires 30 mm clearance to adjacent devices for heat dissipation; zero clearance when using the side-by-side arrangement with the same S00 frame. The spring terminals accept ferruled or solid conductors — strip length is 8 mm for the cage clamp. The breaker integrates directly with SIRIUS contactors in sizes S00 and S0 via a screwless bus bar system, forming a compact motor starter assembly.
